VANKRASN39: proposed math code

proposed math code

New page

==Math Code==
Proposed math code, please check/correct:

<div {{prettydiv|margin-right=70%}}>'''n = trunc[ 1-σ + sqrt[(σ-1)^2+2r] ]'''</div>
{{Equation box|<math>\mathrm{n = \biggl\lfloor 1-\sigma + \sqrt{(\sigma - 1)^2 + 2r)} \biggr\rfloor}</math>}}

<div {{prettydiv|margin-right=70%}}>'''r = (n/2)(n+2σ-1)'''</div>
{{Equation box|<math>\mathrm{r = \biggl(\frac{n^2 + 2n\sigma - n}{2}\biggr)}</math>}}

<div {{prettydiv|margin-right=70%}}>'''σ = (1/2)(1+2r/n-n)'''</div>
{{Equation box|<math>\mathrm{\sigma = .5 + \frac{r}{n} - \frac{n}{2}}</math>}}
